没有这样的 table Sugar ORM

Question

我的 Android 项目中有很多关于 Sugar ORM 的问题。

那是错误：

我的实体 class 是：

    package net.elinformaticoenganchado.sergio.crossfighters;

import com.orm.SugarRecord;
import com.orm.dsl.Unique;

/**
 * Created by sergio on 7/05/16.
 */

public class Plan extends SugarRecord {
    @Unique
    String name;


    // Default constructor is necessary for SugarRecord
    public Plan() {

    }

    public Plan(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

当我尝试执行下一个代码时出现问题：

package net.elinformaticoenganchado.sergio.crossfighters;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;

import java.util.List;

public class addPlan extends AppCompatActivity implements View.OnClickListener{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_add_plan);

        Plan plan = new Plan("Plan1");
        plan.save();

        List<Plan> plans = Plan.listAll(Plan.class);

        for (int i = 0; i < plans.size(); i++) {
            System.out.println("Plan: " + plans.get(i).getName());
        }

    }

    @Override
    public void onClick(View v) {

    }
}

拜托，我需要帮助，我禁用了 Instant 运行选项，就像在每个帖子中所说的那样，但它不起作用。

感谢您的帮助。

Answer 1

这个问题可以通过创建一个空 "migration script file with new version" 来解决。这可以通过以下简单地完成：

创建新的 Sugar 记录 class。
在 Android 清单文件中增加数据库版本。

通过这样做，它创建了新的 table 而没有 dropping/creating 我的旧 tables。

我的版本是1.5

Answer 2

如果您进行数据库修改，则必须删除应用程序并作为新应用程序安装，或者更改数据库版本并编写更改查询。

没有这样的 table Sugar ORM
